Tube Sheet

Tube Sheet

Precision-Engineered Core Components for Heat Exchangers and Boilers

Our Tube Sheets are critical structural components designed to support and seal tube bundles in heat exchangers, condensers, and boilers. Manufactured with high-precision drilling and superior material quality, these tube sheets ensure optimal thermal efficiency and leak-proof performance under high-pressure and high-temperature conditions.

Key Features & Benefits

• Precision Drilling & Tolerance: We utilize advanced CNC drilling technology to ensure hole pattern accuracy, perpendicularity, and surface finish, guaranteeing a perfect fit for tube-to-tubesheet joints (welding or expansion).

• Superior Sealing Integrity: Designed to withstand high differential pressures and thermal cycling, preventing leakage between the shell side and tube side fluids.

• Robust Construction: Available in solid, forged, or clad plates, our tube sheets provide exceptional strength and resistance to corrosion and erosion.

• Customizable Designs: We manufacture Fixed Tube Sheets, Floating Tube Sheets, and Tube Sheets with Expansion Joints to accommodate thermal expansion and stress.

• Complex Configurations: Capable of producing multi-pass partitions, tie rods, and impingement plates as integrated components to meet specific TEMA and ASME requirements.

Technical Specifications

• Dimensions: Custom manufactured to client drawings, ranging from small diameters to several meters (up to 4000mm+).

• Thickness: From thin sheets to ultra-thick plates (over 400mm) for high-pressure reactors.

• Hole Patterns: Triangular (30°, 60°), Square (90°), Rotated Square (45°), or custom patterns.

• Standards Compliance: ASME Section VIII, TEMA, EN 13445, GB/T 151, and customer-specific specifications.

• Surface Finish: Machined to specific Ra values to ensure optimal seal welding or hydraulic expansion.

Available Materials

We supply tube sheets in a wide variety of materials to match the corrosive nature of the process fluid:

• Carbon Steel: ASTM A516 Gr. 60/70, A266, 20MnMo, 16Mn

• Stainless Steel: ASTM A182 F304/L, F316/L, F321, F347, 904L

• Duplex & Super Duplex: F51 (2205), F53 (2507), F55

• Clad Plates: Carbon steel base with stainless steel or nickel alloy cladding for cost-effective corrosion resistance.

• Nickel Alloys: Inconel 600/625, Monel 400/K500, Hastelloy C276/C22

Applications

Our tube sheets are essential components in:

• Shell and Tube Heat Exchangers

• Surface Condensers and Feedwater Heaters

• Chemical Reactors and Pressure Vessels

• Boilers and Steam Generators

• Oil & Gas Refineries and Petrochemical Plants

• Power Generation (Thermal and Nuclear)

Quality Assurance & Packaging

Quality is paramount in tube sheet manufacturing. We conduct rigorous inspections, including:

• Dimensional Inspection: Verifying hole diameter, pitch, and pattern layout.

• Non-Destructive Testing (NDT): Ultrasonic Testing (UT) for lamination and internal defects, Radiographic Testing (RT) for weld integrity, and Dye Penetrant Testing (PT).

• Material Verification: Positive Material Identification (PMI) and Chemical Analysis.

All tube sheets are packed in sturdy wooden crates or steel frames with protective coatings to prevent damage to the machined surfaces and tube holes during transportation.
